| Abstract | ||
| Methomyl (Lannate), Carbofuran (Furadan). Oxamyl (Vydate) and Thiodicarb (Larvin) applied at the recommended rates of application did not affect the amount of total chlorophyll formed sweet potato leaves after the 1st in spray. the only exception is the reduction (13.62%) in the amount of total chlorophyll formed after Furadan application. Generally. the 2nd spray in the reduced significantly total chlorophyll content. Reduction in total chlorophyll after the 2nd spray could be arranged descending order; Vydate (45.91%), Furadan (34.03%). Lannate (32.48%), and Larvin (7.46%). On the other hand, Jarvin caused a stimulating effect on both respiration (11.82%) and nitrification (35.73%) processes. Lannate increased soil respiration only by 24.45%, while Furadan and Vydate did not affect the two processes. | ||
